 What are allergies? The test is relativley painless. It involves placing antigens on the top layer of the skin on the forearm using a prick method. The test takes a few minutes to perform. We get results in about 15-20 minutes.
What is an allergic reaction? Our immune systems are designed to defend us against foreign substances such as bacteria, viruses and toxins. Allergic people have immune systems that are 'too good.' Their bodies wrongly believe certain substances - like pollen or mold - are threats.
When allergic people come into contact with allergens, their bodies make large numbers of antibodies (disease fighting proteins) that bind to cells in the tissue and blood and also make strong chemicals. It is these chemicals - as they move through the body - that cause the symptoms of allergy.
What are the most common allergies? Most of the time, allergic reactions are to pollen grains, dust, molds and foods. They can also happen from contact with animal proteins such as those found on hair, fur or dander; drugs, such as penicillin; and topical agents, such as the oils on poison ivy leaves.
What are the symptoms? Symptoms include watery, itchy eyes, as well as sneezing, runny nose, nasal congestion, and a scratchy throat. The particular symptoms a person has depends on where in the body the antibodies are bound and the chemicals are released.
What is the difference between season and perennial allergies? Seasonal allergens are active only during certain times of the year. Pollens are most common in the spring, grasses in the summer and ragweed in the fall. Perennial allergens are active all year. These allergens include house dust, animal dander, mold spores, foods, medicines, and insect bites and stings.
